To atZZ whom it may concern.-

Be it known that I, GEORGE W. DUDLEY, of Charleston, in the county ofKanawha and State of \Vest Virginia, have invented anew and usefulImprovement in Ty pe-lV ritin g Attachm cuts for Adding-Machines, ofwhich the following is a specification.

My invention is in the nature of a typewriting attachment to thecombined adding and printing machine which was patented by me February18, 1890, No. 55%993. its object is to enable the combined adding andprinting machine to operate upon and print directly on blank-books, suchas ban k-books, pass-books, &c.; and it consists in such reorganizationof the printing-carriagc and its associated parts as will enable ablank-book to be conveniently and quickly inserted into the machine andthe extensions and totals printed directly on the pagesof the same, aswill be hereinafter more fully described with reference to the drawings,in which Figure 1 is an end elevation of the carriage and printingdevices, showing the parts in the position which they occupy in printingupon a roll of paper, the near standard C being removed. Fig. 2 is asimilar view showing the parts in the position which they occupy whenprinting upon a blank-book, and Fig. 3 is a front elevation of Fig. 2.

In the drawings, Z represents the base-plate or deck, from the oppositeends of which rise vertical standards 0 C, connected at the top byhorizontal rod U.

A is the laterally-adjustable carriage-frame, having a ball-bearingsupport X Y V below and a pair of rollers R at the top, which bearagainst the side of rod U. In said ball-bearing support Y is a thin andslotted metal bar running horizontally across the carriage and occupyinga position between the subjacent track-bar V and the superposedtrack-bar X. The track-bar V is stationary and fixed in the standards 0,and the slotted bar Y and track-bar X are connected to and laterallyadjustable with the carriage-frame A. The adjacent edges of thetrack-bars V and X are concaved or grooved to receive and retain theballs I), which are spaced by and retained within the slots of the barY, which is fixed to and moves with the frame A.

Serial No- 592,116. (1T0 motleld To move the carriage-frame A laterallyon this roller-bearing track, a rack-bar E is at tached to the lower endof frame A and meshes with a pinion F on the same shaft with and rigidlyattached to the gear-wheel G. This gear-whcel meshes with a smallergearwheel if on ashaft if, journaled in the hanger 1 below thedeck-plate. This shaft 11 is the same shaft as the shaft 0" shown in myprevious patents, Nos. l,fl93 and 555,039, and the means for rotating itto effect the feed being fully described therein are not shown here andneed not be further described. It is sufficient to say that the rotationof shaft ll through the gears H, G, i and E feeds the frame Aintermittently along in horizontal direction as each letter is printedupon the paper or book carried by the frame A.

At L is shown the paper roll carried in offsetting arms projecting tothe rear from frame B, which latter is hung upon a transverse shaft 13,whose ends are flattened and held rigidly in frame A. The weight of thelaper roll being in the rear of the ball-bearing support unbalancesframes A and B and throws from its own gravity the top of frame Arearwardly and causes its rollers It to bear against and travel upon theguiding trackbar U above. For this action the two frames A and B,although hinged together, act as one frame by reason of a springconnection consisting of coil-springs b, which are wound about shaft 13and strain the frame B forwardly against A to pinch and hold the book,as hereinafter described.

T is an idleroller journaled in the arms S, which are hinged upon therod S, connecting the side frames On the rod S is a coilspring 3 for thepurpose of holding the arms S and roller T in contact with the paperroll L and following it up as the paper is exhausted. It also serves asa brake and also prevents the loosening of the end of the paper when itis run back for the insertion of a book or card.

The frame B carries a platen XV and a rubber-faced feed-roller hi, tothe shaft of which latter is attached rigidly a ratchet-wheel M, whichis operated with a step-by-step movement by pawl P and lover O.

N is a small roller lying in front of feedroller M and journaled in theframe A, and Q is a rod whose upper edge is brought to a knifeedge. Thestrip of paper passes between the rollers M and N and then upwardlybetween the platen XV and knife-bar Q, the latter permittin g the paperto be torn off with a straight line when the work is finished.

In front of the platen XV lie the type-levers T L, whose upper ends areprojected against the paper in front of the platen by an impactbar I B,operated by crank o and operatingshaft, which impact-bar, rising,strikes the el bow of the type-lever and throws it forward. The meansfor operating this impact-bar and crank 0' I do not show, as it is fullydescribed and shown in Fig. 5 of my previous patent, No. 55l,993, andforms no part of this invention.

In Fig. 1 the linep p represents the course of the paper as it isunwound from the roll, but the construction of carriage describedpermits of the use of a blank-book in the place of the paper, so as toenable the machine to print in bank deposit-books, pass-books, and thelike. For this purpose (see Fig. 2) the frame B is tilted back on itsaxial bar B, but is strained forward by coil-springs on shaft 13 with atension sufficient to overcome the weight of roll L, and an openblank-book, with its face to the type-lever T L, is inserted between theroller N and bar Q in front and the platen XV and feed-roll M behind,and is then held by the forward tension of the frame B, being fedvertically through the lever O by hand and horizontally through therack-bar E and gears l G ll.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A type-writer carriage made in two main parts, the rear part havin ga platen and a feedroll, and the front part having two bearings arrangedin a vertical plane one above the other, the said two parts being hingedand provided with a spring for pressing them together to accommodate thereception and vertical feed of a blank-book substantially as and for thepurpose described.

A type-writer carriage made in two main parts,the front part having twobearin g-points for a book arranged Vertically one above another, andthe rear part carrying the platen and feed-roll, and jointed to thefront part,and having a spring connection therewith to press itforwardly to the type-levers but allowit to yield baclnvardly therefromto permit the in- 5 5 sertion of a book substantially as and for thepurpose described.

The combination with the statii'inary standards 0 having track-bar U ofthe laterally-adjustable carriage-frame A,haviugball- 6o bearin X Y V,rollers R at the top arranged to bearagainst the front side of thetrack-bar, and a paper roll projecting rearwariilly to hold the roller Ragainst its track-lntr substantially as and for the purpose described.

4t. The combination with the frame A bearing roller N and knife-bar Q;of the yielding frame 13 bearing platen, feed-roll, and paper roll,substantially as and for the purpose described.

5. The combination with the frame A bearing roller N and knife-bar Q; ofthe yielding frame B, bearing platen, feed-roll, and paper roll, andspring-pressed arms S with idle-roll. T bearing upon the paper rollsubstantially 75 as and for the purpose described.
